Inventor Patented Mar. 3, 1936 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to strainers.

The primary object of the invention is to provide a strainer for milk or other liquids, the parts of which are easily demounted for cleaning purposesand that has in association therewith a sediment basin wherein heavier particles that will not pass through the strainer may settle and collect in the basin.

Further objects of the invention are to provide a strainer of, the character referred to, that is strong, compact and durable and that is very sanitary and may be asembled and dismantled with ease and dispatch, and that is comparatively inexpensive to manufacture and operate.

With the foregoing and other objects in view the invention consists of a novel construction, combination and arrangements of parts as will be hereinafter more specifically described and illustrated in the accompanying drawings, wherein is disclosed an embodiment of the invention, but it is to be understood that changes, variations, and modifications may be resorted to without departing from the spirit of the claims hereunto appended.

In the drawings, wherein like reference characters denote corresponding parts throughout the several views,

Figure l is a side elevation of the strainer in accordance with the present invention in the assembled relation.

Figure 2 is an enlarged vertical section thereof taken substantially on the plane of line 2-2 and looking in the direction of the arrows,

Figure 3 is a side elevation of the disk removed from the assembly,

Figure 4 is a top plan View of the sediment basin removed from the assembly,

Figure 5 is a top plan view of the dome removed from the assembly,

Figure 6 is a top plan view of the disk removed from the assembly.

Referring to the drawings in detail, A indicates the funnel bowl having an open top, and. cylindrical side walls 1 merging at their lower ends with the inwardly and downwardly sloping bottom wall 8. Depending fro-m the center of the bottom wall 8 is a spout 9 having an outlet passage IO. Adjacent the lower end, the outer perip-hery of the spout 9 is formed with a pair of stepped shoulders one above the other, the numeral ll indicating the lower step and the numeral I2 indicating the upper step. On diametrically opposite points on the upper portion of the side wall 1 are secured handles I3. At diametrically opposite points on the outer face of the bottom wall 8 of the funnel bowl A are a pair of bail ears M with which are coupled the eyes I5 on the ends of the legs of the U-shaped swingable metal rod indicated generally at 16. This metal rod has sufilcient flexibility to hold the parts of the strainer inclamped relation when they are in the assembled position. The U- shaped rod it has a substantially straight crown portion ll with a bow 18 in the center of the crown. The bow I8 is directed outwardly.

The sediment basin is indicated at B and this basin is formed with a conical impression IS in the bottom wall which merges with a lateral trough 20 around the margin of the bottom wall. Around the upper edge of the side wall of the sediment basin is an upstanding lip 2| and below the lip is an upper, annular, horizontal ledge 22. Spaced below the ledge 22 is another horizontal annular ledge 23. The outer periphery of a disk 24 rests on the lower ledge 23 and in the center of the disk is an opening which is in alignment with the passage II) in the spout 9 of the funnel bowl. Rising above the disk 24 is a screen sleeve formed with an upper ring 25 and a lower ring 26 supported on the ends of upright rods 27 which form braces for the screen filter. The lower ring 26 of the screen filter is fixed in the opening in the center of the disk. A tubular screen 28 has the upper edge secured to the upper ring 25 and the lower edge secured to the lower ring 26 on the outside of the rods 21.

It will thus be seen that the liquid to be filtered passes through the passage in in the spout and through the screen sleeve, where it is free to pass laterally of the sleeve and any heavy sediment will pass through the opening in the disk 24 and collect in the annular trough 20. It will be understood that the screen sleeve is rigid as distinguished from the limp cloth filter to be presently described.

The outer margin of an annular limp fabric filter cloth 29 is clamped by the edge of a dome to be presently described, against the upper ledge 22 and overlaps the edge of the lip 2| as at 30, all of which will be apparent from an inspection of Figure 2 of the drawings. The filter cloth 29 is supported in spaced relation to the disk 24 when the parts are assembled to provide a chamber 31' between the screen sleeve and the disk 24 and the side walls of the sediment basin, which chamber is substantially bounded by these parts. There is an opening in the center of the filter cloth 29 and the lower portion of the spout extends through this opening while the upper ring 25 of the screen sleeve clamps the filter cloth about the opening against the lower stepped shoulder II on the spout.

To hold the filter cloth 29 in position and also to offer further straining action, I provide a dome indicated generally at C. The zenith of the dome has a round opening about which is a metal ring or hub 32. This ring or hub 32 in the assembled relation fits in clamped relation against the upper step I2 of the spout 9. From the ring or hub 32 radiates circumferentially spaced spokes which slope downwardly and outwardly where the ends are secured to the outer peripheral ring 34. Secured to the lower face of the outer ring 34 and the ribs or spokes 33 and the inner ring 32 is a continuous sheet of metal screen material 35 which completes the configuration of the dome. The outer ring 34 in the assembled relation clamps the margins of the screen cloth on the upper ledge 22 of the sediment basin and holds it clamped against the lip 2|.

The crown ll of the U-shaped rod l6 bears against the bottom of the sediment basin as shown in Fig. 2 of the drawings and holds all of the parts in assembled relation.

To dismantle the strainer for cleaning purposes the rod I6 is swung laterally free of the bottom 01' the sediment basin B. In this position the basin may be removed which separates the dome C from the lip 2|. Then the disk 24 may be slipped from the lower step of the shoulder on the spout 9 after which the. filter cloth may be removed and lastly, the dome may be slipped from the upper step of the shoulder on the spout. To assemble the device, the reverse of the operation will follow.

Having described my invention what I claim is:

1. A milk strainer comprising a funnel bowl formed with a depending spout, a U-shaped rod including a crown portion swingable on the lower portion of the funnel bowl, a sediment basin equipped with a pair of ledges around the side walls one above the other, a disk resting on the lower ledge, said disk formed with a central opening, a rigid screen sleeve rising from the disk and registering with the opening and secured to the spout, a limp filter cloth clamped to the upper ledge at its outer periphery and clamped to the spout at its inner periphery above the screen sleeve and said crown portion of the handle frictionally engaging the bottom of the sediment basin to retain the parts in clamped relation in the assembled position.

2. A milk strainer comprising a funnel bowl provided with a depending spout formed on the exterior with a pair of stepped shoulders, a U- shaped rod swingable on the lower portion of the funnel bowl, a sediment basin equipped with ledges around the side walls thereof one above the other, a disk resting on the lower ledge and formed with a central opening, a screen sleeve having one end supported in the opening and rising into communication with the opening in the spout, a limp filter cloth having the inner periphery clamped against the lower shoulder by the upper end of the screen sleeve, a clamping dome of reticulate formation having the outer periphery bearing on the outer periphery of the cloth and bearing on the upper ledge of the basin and having an opening in the center embracing the upper shoulder on the spout, and the crown of the U-shaped member frictionally engaging the bottom of the basin for clamping the parts in the assembled position.
